Index with repeated values

[Incamus]

Dear all, good afternoon.

Can you help me with this problem?

Table with the code used:

let
Fonte = BD_Geral,
#"Outras Colunas Removidas" = Table.SelectColumns(Fonte,{"Nº CTe", "Nome"}),
#"Linhas Classificadas" = Table.Sort(#"Outras Colunas Removidas",{{"Nº CTe", Order.Ascending}}),
#"Linhas Agrupadas" = Table.Group(#"Linhas Classificadas", {"Nº CTe"}, {{"Tranportadoras", each _, type table [Nº CTe=nullable number, Nome=nullable text]}}),
#"Tranportadoras Agregado" = Table.AggregateTableColumn(#"Linhas Agrupadas", "Tranportadoras", {{"Nome", List.Distinct, "Contagem de Tranportadoras.Nome"}}),
#"Contagem de Tranportadoras.Nome Expandido" = Table.ExpandListColumn(#"Tranportadoras Agregado", "Contagem de Tranportadoras.Nome")
in
#"Contagem de Tranportadoras.Nome Expandido"

Desired result:

As an example of 52, it started with 0 and then went to 1. If there was a third repeated number, it would go to 2, and so on.

Hi @Incamus ,

Please refer the steps below.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUUpMVIrViVYyQjCNEUwTIDMpCc5MTgYzTYHMlBQw0wzITE2FM9PS4MyMDKXYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Nº Cte" = _t, #"Contagem de Tranportadoras.Nome" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Nº Cte", Int64.Type}, {"Contagem de Tranportadoras.Nome", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Nº Cte"}, {{"Data", each Table.AddIndexColumn(_, "Index", 0, 1, Int64.Type)}}),
    #"Expanded Data" = Table.ExpandTableColumn(#"Grouped Rows", "Data", {"Contagem de Tranportadoras.Nome", "Index"}, {"Contagem de Tranportadoras.Nome", "Index"})
in
    #"Expanded Data"
